How the Stock Market Has Changed Since the 1970s
Not all decades are created equally; the 1970s and 1980s were relatively stable despite the oil shock and inflation of the 1970s. However, the advent of the Internet, online trading, the popularity of stock options, high-frequency trading, and the growth of trillion-dollar corporations have made the stock market much more volatile.
S&P 500 Historical Returns 2000 to 2020
2020 to 2023 has been exceptional due to a pandemic crash in 2020, a boom in 2021, and a crash again in 2022. Any monthly statistical reference should exclude the 2020s.

The Seasonal Effect on the Stock Market
There is a seasonal effect, and it does repeat itself. This could be due to retail sales, summer commodities harvest, and the build-up to the Christmas selling period.
Ultimately, the economy’s state and the government’s fiscal and monetary policy stewarding play a leading role here. The ’80s and ’90s were decades of unprecedented growth, and the 2000s was a decade of payback with two severe crashes, the Dotcom bust (2000) and the Financial Crisis (2007); this is reflected in the chart above.
From 1980 to 2000, January to June was positive, and October to December was negative. Only August and September were not 100% positive in terms of gains—10 of the 12 months.
From 2000 to 2009, 5 of the 12 months were negative: January, February, June, July, and September.

Summary
The single best month to buy stock over the last 50 years and in every decade has been October.
Of course, what you buy is key. If you invest in an Exchange Traded Fund that tracks the S&P 500 or any major market index, this trend should hold until the trend changes.
If you invest in individual stocks, this market index analysis will bear little correlation to your purchased stock. The charts above show the performance of all the stocks in the index.
Remember, although a stock may increase or decrease due to the ebb and flow of the underlying market direction, the fundamentals of the stock you purchase, combined with your timing, will ultimately determine the long-term profitability of the investment.

Looking at the average values, isn’t it best to buy stocks at the END OF February and END OF September?

Yes, that is also a good strategy

Want to buy stock for each grandchild. How do I keep them from cashing in immediately after giving them the certificates?
I think it would be best to keep the certificates
It appears that q3 results influence the good buy in Oct & Nov and q4 & YOY for April buying, in other words q1& q2 have less influence on buying trends. q1 & q2 creates un certainty in moods as one is beginning of the year and another is just starts to give signs.
If you are a buy and hold long time investor, would be be prudent to invest in the months when the stock market is falling, so as to have bigger gains for the future ?
Yes, buying at the end of the falling period is a good idea.
As a newly retired couple we will have to sell some ETF S&P 500 shares each year to meet our spending needs. Does your data show a best time a year to sell to get the best price?
Hi Steve, thanks for the question.
The numbers suggest that April is the best month on average for stock price increases. So perhaps the end of April.
thanks
Barry
I have a small flat. If I sell and invest in stock market, will I be able to get the value for buying bigger flat. If possible or say yes, please give me the time period I have to wait to make a valuable consideration for a big flat which is normally avaialbel at 1. to 1.5 cr. At the same time being a greedy like, I do not want to
land in loss and be a bankrupt.
Awaiting your sincere advice at practical experience and exposure to the stock market.
My name is Ramachandran Chandrasekaran
Hi Rama,
I would highly recommend that you do not sell your flat to invest in the stock market with the hope of profiting and buying a bigger apartment. The stock market is volatile, you should only invest a portion of your available capital in stocks.
This is useful and interesting data, but couldn’t you update the charts with 2010-2020 data?
I will think about it for the next update.
