Still a little groggy today? It's only natural; you lost a full hour of sleep yesterday. Put another way, you lost slightly more than 4% of your day on Sunday. As I can personally attest, such losses are never fun. I lost about 4% of the value of my portfolio the other week during the "Shanghai Surprise," which whacked the U.S. market as well.
The combination of these two 4% losses got me thinking that Daylight Savings Time is a good time to review your portfolio holdings. Think of it as a regular necessity -- just like you're supposed to check the batteries in all of your smoke detectors every time the clock springs ahead or falls back an hour.
In my case, I used the opportunity to review why I'm invested in some of my core holdings, which include IBM
My review has also caused me to reevaluate my investments in St. Jude Medical
I can handle 4% drops. Thirty-percent plunges, however, leave me feeling more than groggy. In fact, they leave me feeling angry at myself for not reviewing my rationale for owning the stock a year ago.
