The main (only?) move I've been making is further diversifying out of my company stock. Of course, every single sale of company stock has thus far been a big mistake, but maybe one day I will appreciate the discipline.

From anecdotal evidence, I believe that there are many others with high cash positions waiting for a market correction to put money to work. After a strong months-long rally in the stock market, there seems to be a lot of bearish sentiment out there. I just don't see a substantial correction happening, there are too many people like me waiting for a correction to invest their cash horde. My cash position is even higher than shown, because I didn’t bother to break out the substantial cash holdings in my brokerage and bond accounts. The cash level in these accounts has increased considerably due to some profit-taking I did this week and also due to the maturing of bonds over time.
