SPY Recaptures 200-day – Tips to Reduce Whipsaws and Improve Performance
- Arthur Hill, CMT
200-day Crosses Prone to Whipsaw
SPY and QQQ crossed above their 200-day SMAs with big moves on Monday, and held above these long-term moving averages the entire week. The V-Reversal was extraordinary and SPY seems short-term overbought, but this cross above the 200 day SMA cross is a bullish signal for the most important market benchmark. Despite a bullish signal, long-term moving averages are trend-following indicators and it is important to set realistic expectations.
The chart below shows SPY with the 200-day SMA (blue). This 200-day cross captured two big uptrends since 2020 and foreshadowed the bear market in 2022. Even though these three signals look great, there were plenty of whipsaws along the way. SPY crossed the 200-day SMA 141 times since 2005, which averages 7 crosses per year. Averages can be deceptive because some years have more crosses than others. SPY did not cross its 200-day in 2021 and 2024, but there were 22 crosses between January 2022 and March 2023.
The indicator window shows Percent above MA (1,200,1) to better highlight these crosses. It turns positive (green) with a bullish cross and negative (red) with a bearish cross. The values are the percent difference between the close and the 200-day SMA.

Exit strategies are just as important as entries. The Zweig Breadth Thrust and the 5/200 day SMA cross provided entry signals in April and May. Chartists now need an exit strategy. TrendInvestorPro put forth exit strategies for both signals and these are updated in our reports. This week we covered the gap zones in SPY and QQQ, long-term breadth signals, big moves in metals and continued strength in Bitcoin.
Reduce Whipsaws with Smoothing and Filters
There is no such thing as a perfect indicator. Trend-following indicators are great at catching big trends, but they are also prone to whipsaws (failed signals). Whipsaws are simply the price of admission for a trend-following strategy. We must take the good (big trends) with the bad (whipsaws). As the chart above confirms, trend-following works over time because one good trend pays for the whipsaws.
Chartists can improve 200-day SMA signals with a little smoothing. For example, use a 5-day SMA instead of the close. Since 2005, the 5-day SMA crossed its 200-day SMA 55 times, which averages out to 3 per year. Fewer signals means fewer whipsaws. Also note that this smoothing generated higher returns and lower drawdowns.
The chart above shows the SPY with Percent above MA (5,200,1). This indicator captures the percentage difference between the 5 and 200 day SMAs. Instead of 22 crosses between January 2022 and March 2023, the 5-day SMA crossed the 200-day SMA just 8 times. This is 1 of 11 indicators in the TIP Indicator Edge Plugin for StockCharts ACP.
