The Standard and Poors 500 index (SPX) closed up 35 points today, closing at 6664. SPX opened the week at 6623, setting up a weekly gain of 0.6%. Trading volume ran along the 50 dma all week. SPX is trading within the channel from 6561 to 6705.

VIX, the volatility index for the S&P 500 options, opened the week at 19.5% and climbed as high as 28% this morning but closed today at 20.8%, down 18%. The market has calmed significantly.

I track the movement of the ETF containing the top 100 S&P 500 stocks ranked by beta, SPHB, to monitor the movement of high beta stocks. SPHB closed at 111.1 today, down less than one point or 0.1%. SPHB opened the week at 110 for a weekly gain of one percent. SPHB trading volume ran above average all week with the exception of Thursday.

The NASDAQ Composite index recovered much of last Friday’s collapse, closing at 22,680, up 117 points or 0.5%. NASDAQ opened the week at 22,579, gaining 0.4% for the week. Trading volume ran above the 50 dma most of the week but settled down to the 50 dma today.
Traders opened this week carefully after last Friday’s ugly decline of 2.7%. 

The federal government remains closed, eliminating significant economic and unemployment data, leaving traders in the dark in terms of economic and unemployment data.

Last Friday, I suggested three possibilities for this week:

   • Will calmer minds dominate trading on Monday morning? 


   • Will the lower prices be seen as buying opportunities? 


   • Could the market slide continue lower? 

The S&P 500 stocks gave up 187 points last Friday, but they recovered 41% of that loss this week. I take that as a sign of bullish confidence. We aren’t going over the cliff. It just remains a very volatile market.

My advice for next week remains the same: Stay calm and look for opportunities, but don’t force the trade. It doesn’t hurt to take a pause.

The Standard and Poors 500 index (SPX) plunged today, closing at 6553, down 183 points or 2.7%. SPX opened the week at 6734 for a loss of 2.7% for the week. Trading volume ran along the 50 dma all week but spiked higher today as the market sold off. The S&P 500 index has not traded off this badly since the correction in early April.

VIX, the volatility index for the S&P 500 options, opened the week at 16.7% and traded sideways most of the week, closing Thursday at 16.4%. However, today’s sell-off spiked volatility to a close of 21.7%.

I track the movement of the ETF containing the top 100 S&P 500 stocks ranked by beta, SPHB, to monitor the movement of high beta stocks. SPHB closed at 107.5 today, down 5.4 points or 4.8%. SPHB opened the week at 113.7 for a weekly decline of 5.5%. SPHB trading volume spiked up 274% today.

The NASDAQ Composite index collapsed today, closing at 22,204, down 820 points or 3.6%. NASDAQ opened the week at 22,894, losing 3.0% for the week. Trading volume ran steadily above the 50 dma all week and didn’t even spike higher with the market sell-off today.

Since the market correction hit its low in early April, the market has steadily trended higher, in spite of multiple uncertainties: tariffs, political tension, deportation of illegal immigrants, etc. After the cease fire announcement in the middle east yesterday, I assumed a strong market would make its showing today. That prediction lasted until just before 11 am ET, when news of increased tariff tensions with China hit the markets. From that moment until the close of trading the S&P 500 lost over 2.7%. Ugly!

The federal government remains closed, eliminating significant economic and unemployment data. Shortly before the shutdown, the third and final estimate of second quarter GDP growth came in at +3.8%. That was impressive, but now it seems we are trading largely in the dark in terms of economic and unemployment data.

I have often cautioned my clients about event risk. It is always a surprise and it can really hurt, just as it did today. When these market sell-offs occur on Fridays, analysts always speculate:

   •  Will calmer minds dominate trading on Monday morning? 



   •  Will the lower prices be seen as buying opportunities? 



   •  Could the market slide continue lower? 
 
Stay calm and look for opportunities, but don’t force the trade. It doesn’t hurt to take a pause.

The Standard and Poors 500 index (SPX) set another all-time high today, closing at 6664, up 32 points or +0.5%. SPX opened the week at 6603 for a 0.9% gain for the week. Trading volume ran along the 50 dma all week, with the exception of today’s spike, due to quadruple witching.

VIX, the volatility index for the S&P 500 options, opened the week at 15.1%, and closed today at 15.5%. VIX spiked up a bit to 16.8% on Wednesday with the FOMC announcement.

I track the movement of the ETF containing the top 100 S&P 500 stocks ranked by beta, SPHB, to monitor the movement of high beta stocks. SPHB closed at 110.6 today, down less than one point or -0.1%. SPHB opened the week at 108.0 and posted a gain of 2.4% for the week. Trading volume spiked higher yesterday after the FOMC announcement.

The NASDAQ Composite index set a new all-time high today, closing at 22,631, up 161 points or 0.7%. NASDAQ opened the week at 22,343, gaining 1.3% for the week. Trading volume remained at or below the 50 dma this week except for a move higher yesterday and a large spike today with the quadruple witching today.

This market has lived with the uncertainties of the tariffs, political tension, deportation of illegal immigrants, and the continuous noise of the protesters as background. Apparently, it is becoming old hat, and the market just motors higher, setting several all-time highs over the past two weeks.

The FOMC meeting was the event on traders’ minds for the past several weeks. It was interesting to follow the one-minute chart on SPX through the day on Wednesday. It was choppy and wandering sideways until the announcement at 2 pm ET. Then it spiked higher on the 25-basis point reduction in the federal discount rate. Then it started to weaken, and it plunged during the press conference as Powell struggled to explain the reasoning behind their decision for a 25-point reduction rather than a 50-point reduction, considered more appropriate by many economists.

I often trade the SPX Zero DTE options and Wednesday was no exception. One consequence of the discount rate battle was higher than normal implied volatility at the start of the day for the SPX options. And implied volatility did not decrease much even after the announcement. On the other hand, I gained 37% on my zero dte trade in the midst of the chaos.

The basic economic data remain positive, and the bullish nature of the market seems solid. I was most impressed with the 2.4% rise of the high beta S&P 500 stocks this week. Event risk is our main concern at this point. It won’t take much news or even rumors to cause traders to sell to lock in these gains. Stay calm and stick to your trading rules.

The Standard and Poors 500 index (SPX) opened lower again this morning, influenced negatively by the jobs report and its possible effect on the FOMC meeting's deliberations week after next. Many market analysts are thinking the Fed may finally lower rates at the September meeting. SPX lost 21 points today, closing at 6482 for a 0.3% loss for the week. Trading volume continued to run below average this week until today's trading when volume just touched the 50 dma.

VIX, the volatility index for the S&P 500 options, opened the week at 16.7%, and declined all week to close at 15.2%. The institutional traders are moving to a tentative conclusion that the Fed will lower the discount rate at the September meeting (9/16-17). This is fueling the market’s move higher.

I track the movement of the ETF containing the top 100 S&P 500 stocks ranked by beta, SPHB, to monitor the movement of high beta stocks. SPHB closed at 105.3 today, up 0.4 points or +0.3%.  SPHB opened the week at 102.8 and posted a gain of 2.4% for the week. Trading volume ran along the 50 dma this week, until it rose slightly above the 50 dma today.

The NASDAQ Composite index closed at 21,700, down 7 points or 0.03%. NASDAQ opened today at a new all-time high but could not hold it into the 
close. NASDAQ opened the week at 21,087, up 2.9% for the week. Trading volume remained below average all week.

The overall market has slowly ground higher, pulling back every few days, but rebounding to gain a bit more ground. The gradual decline in VIX reflects that effect. However, the tariffs, political uncertainty, deportation of illegal immigrants, and the continuous noise of the professional protesters in the streets continue as background. 

It is surprising that the markets are ignoring the noise and steadily moving higher. The S&P 500 stocks set a new all-time high this week. NASDAQ set a new 
all-time high today but couldn’t hold it into the close. Similarly, the high beta stocks of the S&P 500 touched its previous all-time high today but pulled back slightly.

I cannot remember a time when the financial news carried so much speculation about the FOMC’s next meeting this far in advance. Normally, it appears on traders’ radar the week before the meeting.

The basic economic data remain positive, but the choppiness will likely continue until after the FOMC announcement on 9/17. Stay calm and stick to your trading rules.

The Standard and Poors 500 index (SPX) opened lower this morning, influenced negatively by the PCE index report that may cause the Fed to leave rates unchanged at the September meeting. SPX gained 42 points today, closing at 6460 for a 0.6% gain on the day and flat for the week. Trading volume continued to run below average all week.

VIX, the volatility index for the S&P 500 options, opened the week at 15.1%, increased to a high of 16.0% today, but closed at 15.4%, effectively unchanged on the week.

I track the movement of the ETF containing the top 100 S&P 500 stocks ranked by beta, SPHB, to monitor the movement of high beta stocks. SPHB closed at 104.9 today, down 1.5 points or -1.4%.  SPHB opened the week at 104.4 and rose 0.5% on the week. Trading volume chopped above and below the 50 dma this week.

The NASDAQ Composite index closed at 21,456, down 250 points or -1.2%. NASDAQ opened the week at 21,466, thus effectively unchanged for the week. NASDAQ’s trading volume remained below average all week.

Many traders have expressed concern about the choppiness of this market. I think we often forget that today’s market reflects a discounting of the predicted future market. Hence, the tariffs spooked the market several weeks ago; then they reversed that doomsday opinion. When Trump announced the meeting with Putin in Alaska, everyone was convinced Putin was going to offer concessions to end the war with Ukraine. But those expectations were naive. Last week’s rally was triggered by Powell’s speech at Jackson Hole, but then market analysts reviewed his remarks more carefully and reduced their enthusiasm.

The market reacted to the PCE index report this morning, up 0.2% from +0.3% last month, or +2.6% year over year. The market consensus feared that result may dissuade the FOMC from lowering rates at the September meeting. Monday’s market opening will show if further reflection calms or stokes those concerns. NASDAQ declined 1.2% this week while the S&P 500 was effectively flat (up 0.03%). Stay calm. The basic economic data remain positive, but traders are running from one side of the boat to the other.

The Standard and Poors 500 index (SPX) opened higher this morning. It appeared that many of the large players believed Powell’s speech was going to hint at lower rates. And shortly after 10 am ET (the schedule for his speech in Jackson Hole), the market was off to the races. The S&P 500 index tacked on 97 points today, closing at 6467 for a 1.5% gain on the day and up 0.3% for the week. However, trading volume continued to run below average all week.

VIX, the volatility index for the S&P 500 options, opened the week at 15.7%, increased to a high of 17.2% on Thursday and then dropped to 14.2% today. Powell’s speech relieved a lot of tension in the markets.

I track the movement of the ETF containing the top 100 S&P 500 stocks ranked by beta, SPHB, to monitor the movement of high beta stocks. SPHB closed at 104.9 today, up 3.4 points or +3.3%.  SPHB opened the week at 103.1 and rose 1.7% on the week. Trading volume spiked higher today as the institutional players started buying high beta stocks, anticipating the market’s continued rise.
 
The NASDAQ Composite index declined most of the week, but that changed today. NASDAQ closed up 396 points at 21,497, up 1.9% on the day but up only 0.6% for the week. NASDAQ’s trading volume remained below average all week but finally hit the 50 dma today.

The market has been struggling this year over a variety of concerns, including the effects of tariffs on inflation, global tensions in Israel and Iran, and the continuing war in Ukraine. The report of +3.0% GDP growth for the second quarter surprised economists several weeks ago but that didn’t seem to affect the market.

The IBD stock market exposure recommendations have been whipsawing up and down all month. First the recommended level of 80-100% declined to 60-80% on August 1, reversed back to 80-100% a week later and recently dropped back to 60-80%. But today’s market rally, triggered by Powell’s speech at Jackson Hole caused IBD to return to the 80-100% recommended stock market exposure. 

Jerome Powell suggested that economic conditions “may warrant” rate cuts at the September meeting, but he was careful to issue many caveats as well. As one may gather from the current economic data, it is easy to predict positive market conditions for the immediate future. I think the current polarization of our political environment causes a significant amount of market anxiety. Today’s market rally was driven by Powell’s remarks this morning, with the Dow hitting a new all time high, the S&P 500 index rising 1.5% (very close to an all-time high) and NASDAQ rising 1.9%.

I will be watching for confirmation of today’s bullish move on Monday, but I expect to find new buying opportunities in this renewed bull market.

Last Friday, the Standard and Poors 500 index (SPX) took a tumble, gapping down at the opening and heading lower. That spooked me, but this week’s trading recovered all of that loss, although it was a rough and choppy ride. SPX opened the week at 6272, for a weekly gain of 1.9%. Trading volume was at or below average all week.
 
VIX, the volatility index for the S&P 500 options, opened the week at 19.6% and steadily declined to a close of 15.2% today. 

I track the movement of the top 100 S&P 500 stocks ranked by beta, SPHB, to monitor the movement of high beta stocks. SPHB closed at 101.4 today, up less than one point or +0.4%.  Trading volume fell all week. The large players sold their high beta stocks, taking a lot of risk off the table.

The NASDAQ Composite index posted a stellar week, gaining 207 points to close at 21,450, matching its previous all-time high on 7/31. NASDAQ opened the week at 20,854, setting up a strong weekly gain of 2.9%. Surprisingly, NASDAQ’s trading volume remained below average all week.

The market has been struggling this year as various commentators have predicted the tariff negotiations will lead to recession and renewed inflation. 
A few weeks ago, the report on GDP growth for the second quarter surprised economists with a reading of +3.0%, but that didn’t seem to gain any traction. Global tensions in Israel, Iran and the various terrorist groups continue to make headlines.

The latest IBD market exposure recommendations, moving down on August 1 and then reversing back higher just a week later show how the mood of market participants is swinging back and forth almost daily. The S&P 500 index made a dramatic move lower last week and yet recovered all of those losses in just one week. Market analysts are spooked by the news feeds even when they know the economic data are solid. The sum of this current form of “yellow journalism” causes the large institutional players to hit their sell buttons quickly but then they fear they may be missing the boat and they hit their buy buttons. 

The essence of free market forces is the open consideration of future risk and planning hedging protection. My analysis of the economic news leads me to a moderately optimistic view of the future economy. Certainly there are uncertainties but that is nothing new. The extreme volatility of the current markets is disconcerting, and I find myself surprised that my trading positions are doing well. Take a deep breath and calm yourself. We have to find the balance between the doomsday gurus and the naivete of the rose colored glasses crowd.

Just as I was becoming comfortable with this bullish market, the Standard and Poors 500 index (SPX) gapped open downward today and closed at 6238, down 101 points or -1.6%. SPX opened the week at 6398, for a weekly decline of 2.5%. Trading volume spiked higher on Thursday and Friday. 

VIX, the volatility index for the S&P 500 options, opened the week at 15.2%, increased on Thursday and spiked up as high as 22% today, closing at 20.4%. 

I track the movement of the top 100 S&P 500 stocks ranked by beta, SPHB, to monitor the movement of high beta stocks. SPHB closed at 100.9 today, down 1.9% today and down 3.2% for the week. That illustrates classic "risk on" behavior. 

The NASDAQ Composite index closed today at 20,650, down 472 points or 
2.2%. NASDAQ opened the week at 21,176, setting up a weekly loss of 2.5%. NASDAQ’s trading volume was roughly flat for the week.

Uncertainties have ebbed back and forth this year over tariff negotiations, inflation, Ukraine, and Iran/Israel. Until this week, those concerns had appeared to be easing. However, it seems like the Fed’s decision to not lower the discount rate started a temper tantrum of sorts on Wednesday and the tariff deadlines today added to those uncertainties.

As I examined the current economic data on Briefing.com, I was struck by its incongruity with the market’s behavior this week. Perhaps the market is discounting future uncertainties?

The Standard and Poors 500 index (SPX) closed today at 6389, up 25 points or 0.4%. SPX opened the week at 6305, for a weekly increase of 1.3%. Trading volume ran along the 50-day moving average (50 dma) all week. 

VIX, the volatility index for the S&P 500 options, opened the week at 16.9% and declined all week, closing today at 14.9%. Volatility has been steadily declining for the entire month of July.

I track the movement of the top 100 S&P 500 stocks ranked by beta, SPHB, to monitor the movement of high beta stocks. SPHB closed at 103.7 today, up 0.8% today and up 0.7% for the week. The high beta stocks of the S&P 500 have been steadily rising since late May, a very bullish sign. 

The NASDAQ Composite index closed today at 21,160 , up 50 points or 
0.2%. NASDAQ opened the week at 20,960, setting up a weekly gain of 0.95%. NASDAQ’s trading volume ran above the 50 dma all week.

The market’s worries about tariff negotiations, inflation, Ukraine, and Iran/Israel appear to be lessening. All of the broad market indices continue to make new highs. Most bullishly, the high beta stocks of the S&P 500, SPHB, have been steadily trading higher since May.
The earnings announcement cycle began last week, but market reactions have been muted, without any significant market-moving surprises thus far. The bullish trend appears more solid each week.

The Standard and Poors 500 index (SPX) closed today at 6297, virtually unchanged from yesterday. SPX opened the week at 6255, for a weekly increase of 0.7%. Trading volume ran along the 50-day moving average (50 dma) all week. 

VIX, the volatility index for the S&P 500 options, opened the week at 17.7% and declined, closing today at 16.4%. This VIX chart is almost identical to last week’s chart.

I track the movement of the top 100 S&P 500 stocks ranked by beta, SPHB, to monitor the movement of high beta stocks. SPHB closed at 102.5 today, up 0.5% today and up 1.6% for the week. This steady rise in the high beta stocks relative to a flat week with the S&P 500 stocks is a bullish signal.

The NASDAQ Composite index closed today at 20,896, up 11 points or 
0.05%. NASDAQ opened the week at 20,593, setting up a weekly gain of 1.5%. NASDAQ’s trading volume ran at or below the 50 dma with the exception of Thursday.

One of the larger uncertainties worrying analysts about the US economy was tariff negotiations and the effect on inflation. That concern appears to be softening with the latest PPI reading coming in unchanged for June and up 2.3% year over year. CPI reported an increase of 0.3% for June but is only up 2.7% year over year. Those reports seemed to be calming markets this week.
