Yeah, something can be learned.
For one, if this is a bottom coming up soon - it would be interesting to see which prior leaders never return from the abyss and which may continue to lead.
More importantly, hanging onto momo stocks that go out of favor with each Bear Market will decimate a portfolio if held.
No, all these stocks won't always be market leaders.
IBD excerpt (today): "The start of that correction basically coincided with a then-record peak for oil prices. Of course, oil marked many more peaks in late spring and early summer, as booming global demand, supply concerns and other factors combined to send crude prices on a rocket ride."
"Despite the broad market's correction, the energy sector, as well as some other raw materials groups, kept climbing, riding along with soaring commodity prices. Those groups were just about the only ones that fared well as the market's woes mounted.
But on Thursday, many of those commodities stocks, especially top-rated oil issues, tanked."
Take a look at the snapshot of all those that fell on an otherwise "up" day.
