On Thursday, March 15th, the S&P 500 made a new 900 day high. With the S&P 500 re-visiting prices it hasn’t seen in almost 5 years, I thought it would be interesting to look at what happens after the index makes significant new highs.
Buy SPY at the close if
- SPY closes at a new X day high
Sell SPY at the close Y days later.
No commissions or slippage included. All SPY history used.
Thoughts and Caveats:
Because the market was making significant new highs in October of 2007, the results show the impact of the bear market, starting around day 65. As the trades are being held for 100 days, any trade initiated in October 2007 was held through the beginning of 2008. Ouch.
On the brighter side, a new high of 50 days or greater has seen a surge during the last 25 days of the holding period. This surge appears to be the relatively normal result of buying during a bull market.
It should be noted that a new 900 day high generated the highest return.
Sample size grew as the X day new high number decreased.
The Buy-n-Hold return was calculated by chopping SPY performance into 100 day segments and then averaging those segments.
The bottom line is that save for a new Armageddon a la 2008, the market has tended to keep climbing after making a significant new high.

Wood – love LOVE these studies – they’re interesting, thought provoking and always good reads.
Glad to hear it Cheese!
I’m wondering if there’s a way to get an RSS feed of only your blog posts from this website, Woodshedder? Any ideas?
No offense to the other iBC writers.
What happens? Inflation happens. Soon. A lot.
Nice play, Woodrow.
Sorry about your Rams this weekend… I was hoping for another push to the Final Four.
