To Evaluate Performance of a Major Stock, Compare it with the Average/Index it Belongs to

- Intended for Start-up Analysts and Researchers -

To understand the performance of a major stock, compare it with the primary index/average it belongs to. Since Goldman Sachs (GS) is one of the 30 stocks that comprise the Dow Jones Industrial Average (DJIA), its performance should be compared with the DJIA, a priori.

The top chart shows the weekly closing prices of both between 7/01/17 and 6/30/18. Though GS outperformed the DJIA through 3/10/18, it completely fell apart ever since, leading to the retesting of the 7/3/17 price. The DJIA, on the other hand, registered a solid 13.34% price appreciation during this one-year period.

The DJIA (middle chart) shows the meteoric rise from 21,400 to 26,600 (24.30% gain) through 1/22/18, but gave back 11% since then. Nonetheless, the remaining annual gain was noteworthy.

GS (bottom chart) performed equally well through 3/5/18, moving up from 222 to 270, with a gain of 21.32%. Unfortunately, that was also the tipping point leading to a linear decline. The trendline confirms the continued awful decline.

FYI - since the weekly closing prices are already smooth, you do not need to add the moving average trendline. When you use the daily closing prices, you do.
