who is getting nervous

We have improving US and EU economies, and China should keep growing. Stock markets are high but there is also a lot of leverage again.

I have been reducing at every opportunity and still have more capital in shares than ever before.

My instincts are telling me there is more risk on the downside than the upside and it is not a time to put more money into shares, but it seems there is plenty of money flowing into shares at present pushing up valuations.

Anyone else getting nervous?
