리스크 대비 보상 비율이 이해가 잘 안 돼요 🤔

Your assuming buying 1 share. You can place any stop you want and depending how much you hit will alter the stop value. So you can buy a $100 stock with a $1 stop loss and buy 100 shares so your stop loss is now £300 then target $103 for example for your 1:3RR and make $300 from this move.

Risk-to-reward is all about the ratio between your potential loss and potential gain. If you're putting in $100 with an R:R of 1:3, it means you're risking $100 to potentially make $300, but that doesn't mean you directly make $300 from any stock move. It's the strategy of scaling your positions and managing your trades that allows you to achieve that ratio. To trade with low amounts, look into fractional shares or leverage, but be cautious as those come with different risks and mechanics.

Its called leverage

Leverage and position sizing are new concepts you can research to answer your question.

Share prices above $1k are rare. There are plenty of large stocks (NFLX, UBER, PFE, PYPL, etc) with share prices under $100. When people say you can start small, they mean with these stocks, not stocks that cost $7k/share. That, and most brokers these days allow fractional shares.

RR is really more about technical analysis and where you believe the price action will go.

Let's assume a stock price is $100 and you have a 1:2 RR. In order to make a 1:2 work, this $100 stock needs to have the potential, as determined by technical analysis, to go to $102. It also needs to have a plausible stop no lower than $99. Getting stopped out loses you $1, while making it to your target gets you $2 in profit.

If the stock is choppy and regularly dips below $99, this trade no longer meets your 1:2. You risk getting stopped out if you put your stop at $99 during normal trading range, and placing your stop lower than $99 violates your 1:2 R:R. Likewise, if there isn't room for the stock to run to $102, you also don't meet your R:R. You'd be risking $1 and not really have much chance of getting to $2 in profit

Related to this is the 1% rule, where you never risk more than 1% of your account on a single trade. So in the example above, if you have a $25k account, the most you should risk on a single trade is $250. If you're risking $1/share, that means you can only have a 250 share position. But sizing positions is a separate issue from whether or not the trade can actually work within your risk tolerance.

What all this means is that if you never risk more than 1% of your account in any given trade, and you always keep a 1:2 RR, as long as you're winning slightly more than 1 out of every 3 trades (or better), you're making money.

Follow the example:

Stock XYZ current price $100.00

Entry Long with $50 of risk on the trade and a stop at $99.00

Step 1) Entry price - stop price = distance to stop price

$100 - $99 = $1 distance to stop price

Step 2) Amount risked on trade (this is what you decide) / distance to stop = # of shares to take for trade

$50 / $1 = 50 shares

So in this example you would enter long with 50 shares with a stop at $99 in order to risk $50 on the trade. If price rose to $101 then you would make $50 profit (50 shares X $1) and that would be 1:1 risk to reward.

Simple example but hope that helps!
