If you're looking, you can see a continued trend of "tells" that the stock market is topping-out.
See my blog entitled A Stock Market Peak is Probably Near from back in mid-March. There were a lot of good examples in that blog. Since March, several important indices are at new all-time highs, so it's possible that I am wrong. While the Dow may be at new highs, the Russell 2000 and Nasdaq are down for the year to date.
Fraudulent behavior often accompanies market peaks. A good example is from Zero Hedge. The article talks about the price-to-earnings ratio of for the Nasdaq iShares Biotech ETF with the ticker symbol IBB. It's reported by iShares to have a PE of 41 times. Jim Grant, a sane and observant scholar and analyst, noted on CNBC that the reported PE of this security is basically a fraud.
Contained in the fine print of the report is the explanation that any security that has a PE greater than 60X is figured as 60X, not the actual PE. It turns out that only 25 out of 122 companies in the index ETF have price-to-earnings ratio UNDER 60X! Check this out:
