What is short selling?
Trading falling markets, also called "short selling", lets you profit when prices decline. CFDs simplify the process — you open a short position, the price falls, you close at a profit. You do not have to borrow shares or worry about a buy-in, as with traditional short selling on an exchange. CFDs eliminate most of the logistical barriers of short trading.
Traditional short selling on an exchange requires borrowing shares from a broker, selling them at the current price, then buying them back at a lower price and returning them to the owner. CFDs on indices, commodities or forex bypass this process — you trade the pure price difference. It is simpler, faster and cheaper.
The market does not rise forever. Historical corrections run 10-30%, and recessions 30-50%. A trader who ignores half the market rejects half the opportunities. But shorting demands more respect than going long.
CFDs and short selling
Short positions are a natural element of a balanced strategy. The market falls as often as it rises — ignoring half the market means giving up 50% of the opportunities. Professionals do not predict the market's direction; they simply react to signals in both directions. If technical analysis shows weakness at resistance, they open a short. If it shows strength at support, they open a long.
Example: the S&P 500 is trading at the strong 5500 resistance level, RSI reads 74 (overbought) and the candlestick chart forms an "evening star" pattern. That is a short signal — not because "the market has to fall", but because technical analysis points to a probable correction from that level.
The risk of a short position
The risk of a short position is theoretically unlimited — price can rise indefinitely, but it can only fall to zero. In practice, disciplined use of stop-losses caps this risk at a known level. Short positions require extra caution because markets have a long-term upward trend — trading against the trend is statistically harder.
The phenomenon called a "short squeeze" is a sharp price rise that forces short positions to close, fuelling further gains and forcing yet more shorts to cover. GameStop in 2021 is the classic example — traders shorting the stock lost billions when the share price rose from 20 to 480 USD within a few weeks.
The best moments for a short position
The best windows for short positions are: peaks after strong upward moves (exhaustion), bad fundamental data (falling company earnings, rate hikes), and breaks of key support levels. Avoid opening shorts in a strong uptrend — "the market can remain irrational longer than you can remain solvent", as Keynes wrote.
Specific short signals: RSI divergence (price rises, RSI falls), a break of the uptrend, a "shooting star" candle at resistance and a MACD bearish crossover. Every signal must be confirmed by at least one additional tool — a single indicator is not enough.
Summary
Trading falling markets is a powerful tool in the CFD trader's arsenal. It allows profits in all market conditions, but it demands greater discipline, wider stop-losses and a shorter time horizon. Treat the short position as a shield in a defensive portfolio, not as your main strategy of attack.
