I was watching the ABC World News the other evening, and I was struck by the commercials they ran. The target demographic is obviously an older crowd (and since I was watching, I guess that includes me). Advertised products within the short 30-minute newscast addressed a variety of age-related ailments like low-T, erectile dysfunction, overactive bladder, constipation, hemorrhoids, and loose dentures.

Last week, the Dow and S&P 500 large caps hit five-year highs, the Russell 2000 small caps and the S&P 400 mid-caps made all-time highs, and the Nasdaq recorded a 12-year closing high. But some investors are evidently showing concern that it has all come too far too fast.
