When the market crashes, should I sell bonds and buy equities for the inevitable recovery? 
The problem with the proposed plan is the word "inevitable". There is no such thing as a recovery that is guaranteed (though we may wish it to be so), and even if there was there is no telling how long it will take for a recovery to occur to a sufficient degree. There are also no foolproof ways to determine when you have hit the bottom. For historical examples, consider the Nikkei. In 2000 the value fell from 20000 to 15000 in a single year. Had you bought then, you would have found the market still fell and didn't get back to 15k until 2005...where it went up and down for years, when in 2008 it fell again and would not get back to that level again until 2014. Lest you think this was an isolated international incident, the same issues happened to the S&P in 2002, where things went up until they fell even lower in 2009 before finally climbing again.  Will there be another recession at some point? Surely. Will there be a single, double, or triple dip, and at what point is the true bottom - and will it take 5, 10, or 20+ years for things to get back above when you bought? No one really knows, and we can only guess.  So if you want to double down after a recession, you can, but it's important you not fool yourself into thinking you aren't greatly increasing your risk exposure, because you are.
