TDAmeritrade's Investor Movement Index is not based on what the institutions and banks are trading, but on the real investing of Main Street investors. After it had dipped in July, the IMX bounced higher in August, by 5.95% to 5.16.
"We are also excited to introduce our new "fast" beta weighting within the thinkorswim platform to complement the traditional beta weighting calculation," Sherrod explains. "The calculation of fast beta uses one year of pricing data for the weighting symbol.This calculation is mathematically weighted such that more recent pricing behavior has a greater impact on the calculation than older pricing data. For example, NFLX has a traditional beta weighting of 0.77, while the fast beta weighting is 2.3. Momentum traders and long-term investors are really receptive of this new metric as a means of screening stocks."
