what is gapping 
gapping occurs when the price of a stock or another asset opens above or below the previous day s close with no trading activity in between a gap is the area discontinuity in a security s price chart gaps may materialize when headlines cause market fundamentals to change rapidly during hours when markets are typically closed for instance the result of an earnings call after hours gapping may also refer to the difference or spread in rates at which banks borrow and lend the dynamic gap measures how assets money held and liabilities money loaned change over time understanding gappinggapping can occur in any instrument where the trading action closes and then reopens stocks do this on a daily basis currencies trade continuously throughout the week but can still experience gaps between when the market closes before the weekend and reopens after gapping may be partial or full in nature partial gapping occurs when the opening price is higher or lower than the previous day s close but within the previous day s price range full gapping occurs when the open is outside of the previous day s range gapping especially a full gap shows a strong shift in sentiment occurred overnight types of gappingthere are different types of gaps depending on the size of the gap and where they occur within the overall trend of the asset each of these types of gaps can be full or partial gaps common gaps are typically partial gaps as the price doesn t move significantly however in some cases the price may not move much yet and still end up as a full gap meanwhile breakaway runaway and exhaustion gaps tend to be full gaps common gaps occur frequently have little significance and are when the opening price is slightly different from the prior closing price the lack of a significant price move on the gap or after shows the gap is common a breakaway gap occurs when the price moves above a significant resistance area or below a significant support area on the gap it can also occur after the price has been in a tight trading range or when it moves out of a chart pattern the breakaway gap indicates the start of a strong trending move is typically a large gap and the price tends to follow through in the gap direction over the next few weeks runaway gaps occur during a strong trend and show that the trend is still strong enough to cause a gap in the trend direction in hindsight these are gaps that occur mid trend as the trend is picking up steam they are typically large and the price tends to follow through moving in the gap direction over the next few weeks tradingviewexhaustion gaps occur near the end of the trend they are typically caused by stragglers jumping onboard late in a trend after having regretted not getting in earlier once the price gaps are higher on this last push of demand there are very few traders left to keep pushing the price in the trending direction a reversal tends to follow within a few weeks gapping and stop loss ordersa trader can have a stop loss order filled significantly below their stop loss price for a long position due to gapping for example a trader may buy a stock on the close at 50 and place a stop loss order at 45 the next day before the market opens the company issues an unexpected profit warning and the stock opens at 38 the trader s stop loss order now becomes a market order because the stock s price is below 45 and gets filled at the next available price which is the 38 open traders can reduce gapping risk by not trading directly before company earnings and news announcements that are likely to have a material impact on a stock s price during periods of high volatility reducing position size helps minimize losses caused by gapping a trader in a short position can also get caught in a gap resulting in more significant losses than expected a trader may be short at 20 with a stop loss at 22 the stock closes at 18 in a profitable position for the trader but overnight another company expresses its interest in buying the company and the price opens up the next day at 25 the trader is punched out of their position at 25 not 22 resulting in an extra 3 per share loss gapping trading strategiessome traders use gaps for analytical insight for example if a gap occurs relatively early in a trend then it is probably a breakaway gap or a runaway gap which lets the trader know the price likely has further to run other traders use gaps for trading purposes they may enter positions after a gap occurs these strategies are called playing the gap day traders often refer to this strategy as the gap and go a position could be taken on the day the stock gaps with a stop loss order usually placed beneath the low of the gap bar the gap should occur above a significant resistance level and trade on heavy volume to increase the chances of a profitable trade alternatively traders could wait for prices to fill the gap and place a limit order to buy the stock near the previous day s close a similar strategy to the one above except in this case the trader enters a short position following a gap down contrarians may use a fading strategy to exploit gapping traders could take a trade in the opposite direction of the gap under the premise that most gaps tend to be filled over time a stop loss order is placed above the gap bar s high following a gap up with a profit target set near the previous day s close for a gap down the trader buys places a stop loss below the gap bar s low and sets a profit target near the previous day s close breakaway and runaway gaps can signal that there is more trend left to take advantage of for trading opportunities therefore following one of these gaps a longer term trader may initiate a position in the direction of the gap typically looking for gaps higher they may hold onto the trade until an exhaustion gap occurs or a trailing stop is hit letting them know to get out gapping often plays into candlestick technical patterns as well such as with the up down gap side by side white lines pattern or the upside gap two crows pattern example of gappingsome stocks have frequent gaps while others have fewer nearly all stocks are susceptible to experiencing a gap following earnings or other major corporate announcements such as a takeover bid a stock may also gap because the overall market moves sharply for example if the s p 500 experiences a volatile move lower one morning many stocks will gap down as a result in analyzing the chart of meta formerly facebook which is shown below the stock had a number of significantly large price gaps following earnings announcements it also had other gaps over the period shown which are marked on the chart image by sabrina jiang investopedia 2021the chart also illustrates that a breakaway gap doesn t always need to be in the trending direction a strong gap against the current trend could signal a break or reversal in the other direction take for example the 217 50 close high point on the chart just under 220 the following day the stock opened at 174 89 just below the 2nd arrow from the left after a worse than expected earnings announcement in other words investors who had purchased meta at 217 would have lost nearly 20 overnight showing how devastating a gap can be even if using a stop loss
