Readers of this blog should know by now that the Dow
Theory works. The measure of “working” is twofold: (a) drawdown reduction and
(b) outperformance versus Buy &
Today, I’ll briefly explore the short side. What
happens when we go short instead of going to cash when the Dow Theory signals a
SELL (primary bear market)? Can the Dow Theory swim against a secular bullish
tide? The answer is: YES. Even when confronted with a secular bull market
(which may be recently over), the Dow Theory manages to be profitable, and it
is not an oddity, as the Dow Theory managed to outperform B&H going long precious
metals and oil when the secular trend was negative, as was explained here and here.
I performed two tests with TradeStation®:
The first one entails shorting EDV (the long-term duration bond ETF). The second one is going long TTT (inverse bond ETF). We had the following rules:
1. When a primary bear market was signaled, I shorted EDV (or went long
TTT), and when a primary bull market was signaled, I covered EDV (or sold TTT).
2. I shun the long side. Only short and covering to isolate the shorting ability of the Dow Theory fully.
3. The test spanned from 12/26/2007 (first short) to 4/26/2022. For TTT, the test started on 4/27/2012
4. Start equity: USD 10,000
5. The Buy (cover)/Sell (short) signals were derived using the TLT & IEF pairs. You may find the specific rules here.
Below are the results for EDV:
The Profit Factor for a "short" trade against a mostly bullish market during the tested period is excellent: 3.25. The profit factor is the ratio between realized profits a losses. The current open short position with an unrealized profit of $2,755 has not been computed, as we still don't know how it will end. Had it been included, the P.F. would have been much higher.
During the 14 years, three months, and 29 days tested, there were 12 closed trades. The current open trade is number 13. Hence, we get, on average less than one short per year—no overtrading.
The 12 closed trades netted out a realized profit of $
6,511. The 13th open trade shows an unrealized profit of $ 3,187 for a total
profit of $9,698. This is almost 100% on the starting equity.
The total time in the market was 44.95%. So if we
adjust for time invested, the Dow Theory scores a very nice return.
However, shorting EDV may not be the only way to bet on higher interest rates. Another option may be to buy an inverse ETF like TTT. Since TTT's inception date was later than EDV, we got fewer trades, as the first short (long TTT) was taken on 4/27/2012.
There was a total of 7 round trades. The 8th trade is still open. The Profit Factor amounts t0 1.63 (based on the seven closed trades). If we took the 8th open trade, it’d be 2.58.
The realized profit amounts to $ 2,526. The unrealized profit is $3,841, for a total profit of $6,367. This amounts to 63.67% made on the start equity in almost ten years. 57.14% of the closed trades were winners. While broadly in sync with the Buy (cover) /Sell (short) signals given by the pair TLT & IEF, TTT is less in gear than EDV, which should not come as a surprise.
The good news is that irrespective of the way we short (outright or through an inverse ETF), the Dow Theory managed to be profitable shorting even when confronted with a period of overall rising bond prices. Couple these results with the good results attained by the Dow Theory going long with oil and precious metals swimming against a bearish tide, as you'll get an idea as to its robustness. So Dow Theorist Hamilton was right when he suggested that the Dow Theory could be applied not only to US stock indexes. It can even work on the short side against a secular bull market.
