The Total Short Ratio ("TSR") shows the percentage
of short sales to the total volume on the New York Stock Exchange.
Interpretation
As with the Public Short Ratio, the Total Short
Ratio takes the contrarian view that short sellers are usually wrong.
While the odd lotters are typically the worst of the short sellers,
history has shown that even the specialists tend to over-short at market
bottoms.
The TSR shows investor expectations. High values
indicate bearish expectations and low values indicate bullish
expectations. Taking a contrarian stance, when there are high levels of
shorts (many investors expect a market decline), we would expect the
market to rise. Likewise, extremely low levels of short sales should
indicate excessive optimism and the increased likelihood of a market
decline.
The interpretation of all of the short sale
indicators has become more difficult recently due to option hedging and
arbitrage. However, they are still helpful in determining overall market
expectations.
Example
The following chart shows the New York Stock
Exchange and a 10-week moving average of the Total Short Ratio.
I drew "buy" arrows each time investors were
excessively bearish. In hindsight, each of these turned out to be
excellent times to enter the market.
Calculation
The Total Short Ratio is calculated by dividing the
total number of short sales by the total number of buy and sell orders.
Both of these figures are reported weekly (on Fridays) by the NYSE.
