Never average down: why early is wrong

Education only, not financial advice. See the full disclaimer.

About the sources. Jesse Livermore (1877–1940) was a US stock speculator. How to Trade in Stocks (1940) is the book published under his own name, and it is the only Livermore source used here. Reminiscences of a Stock Operator (1923) is a different book: journalist Edwin Lefèvre wrote it as a story narrated by a fictional trader, Larry Livingston, who is widely understood to be modeled on Livermore. We don’t quote that character as if he were Livermore. The bold house rules below are Ratigan Capital adaptations, not historical quotes, and nothing here claims to describe how Livermore actually traded.

What you will learn

• Livermore’s warning against averaging losses and the reasoning behind it.
• The arithmetic of averaging down versus a fixed risk budget.
• Why Ratigan Capital treats “early” as “wrong” until price says otherwise.

The idea

In How to Trade in Stocks, Livermore calls it foolhardy to make a second trade when the first shows a loss, and tells the reader never to average losses. In the chapter “Money in the Hand” he walks through a buyer who buys at 50, buys again at 47 to lower the average, and is then holding double the worry as the price keeps falling. He also writes that a margin call is a sign you are on the wrong side and should not send good money after bad.

Our house rules Never Average Down and Early Is Wrong adapt this. If price moves against the entry, the market has not yet agreed with you. Under this process rule, your timing counts as wrong until it does, whatever happens later. This is how we grade our own trades. It isn’t a claim that entering before a signal always fails.

The mechanism (hypothetical numbers)

You plan to risk $100. You buy 50 shares at $50 with a stop at $48 ($2 × 50 = $100 risk).

Price drops to $49. You buy 50 more “at a discount.” Average is now $49.50 on 100 shares. With the same $48 stop, the risk is $1.50 × 100 = $150, 50% above plan. That’s before fees and slippage, assuming the stop fills exactly at $48. If you also move the stop lower “to give it room,” risk grows further. You have increased exposure exactly when the evidence for your idea weakened.

Adding to a winner (sometimes called pyramiding) is different: the first position already shows a profit, and the stop can be raised so total risk stays inside the budget. That is a different mechanism, and it still needs a written rule.

IF–THEN example (hypothetical, educational)

• IF my position shows a loss, THEN no adds of any kind. The only allowed actions are hold to the stop, or exit early per rule.
• IF I want to add because “it is cheaper now,” THEN I write the new total risk in dollars. If it exceeds my planned risk, the add is rejected.
• IF the stop is hit and the stock later rallies, THEN I log it as “early = wrong, rule followed” and do not count it as a mistake.

Limitations

• Some long-term investing approaches deliberately buy more of diversified funds as prices fall, on a schedule, without leverage. That is a different activity with different risks; this rule is about short-term trades with a defined invalidation.
• Following this rule does not stop losses. It caps how one bad idea can grow.
• Real losses can be larger than the plan. Fees, slippage and gaps add to the $150 in the example above.

Exercise (paper journal)

1. Find any past trade or paper decision where you added to a loser, or wanted to.
2. Recompute: planned risk, actual risk after the add, and outcome.
3. Write the dollar difference between the two risks.
4. Add a line to your pre-trade template: “Adds allowed only if position is in profit and total risk stays ≤ $____.”

Check your understanding

You risk $100 on 50 shares at $50, stop $48. You add 50 shares at $49, same stop. What is the new risk?

Average $49.50, 100 shares × $1.50 = $150, which is 50% over plan.

The stop hits, then the stock rallies 20%. Was following the rule a mistake?

Not by itself. Under our process rule, early counts as wrong at the time. The process stayed inside the risk budget; review the rule only across a sample.

Takeaway

A lower average is a bigger bet on a weaker idea. In active trades with a defined stop, our rule is simple: no adds to losers.
