Realty’s $270M Plunge to 432nd Rank as Shares Dip 0.63%

On October 2, 2025, Realty (O) recorded a trading volume of $0.27 billion, reflecting a 20.98% decline from the previous day’s activity and ranking it 432nd among the busiest stocks in the market. The real estate investment trust closed the session with a 0.63% decline in its share price.

Analysts noted that the drop in trading volume could signal reduced short-term investor interest in the sector, though the stock’s price movement remained within a narrow range consistent with its historical volatility. Market participants are closely monitoring broader real estate equity trends as well as macroeconomic signals, including interest rate expectations, which traditionally influence REIT valuations.

To build a sound back-test I need to confirm a few practical details first: Universe—Do you want this run over all U.S. listed common stocks (NYSE + NASDAQ + AMEX), or a different market/universe? Rebalancing mechanics—Each day we rank stocks by that day’s dollar trading volume, select the top 500, and enter positions the next trading day. Should we exit all of them at the next day’s close (i.e., 1-day holding period), or at the next day’s open? Weighting—Equal-weight each of the 500 names, or weight proportional to their dollar volume? Transaction costs / slippage—Include a standard round-trip cost (e.g., 5 bp each side), or ignore trading costs? Once I have those specifications I can generate the execution signals and run the back-test from 2022-01-03 (first trading day of 2022) through today.
