Short term price action...5 Mar 2024 09:13
Re short term price movements, I'm not sure how much people realise that most trading these days is algo driven, in other words computers make trading decisions according to the algos with which they have been programmed. Algos are a series of stages, so if x happens then you need to do Y etc.
I watch small cap Nasdaq stocks most days which are high % gainers on the day with very high volume because news to do with that company has just been released. When the news comes out then you often see in the charts several huge green candles with very high volume when the market opens. This is because the computers have registered the news, and are programmed to jump in immediately. So volume ( shares changing hands ) goes through the roof for a short while. Then when certain levels have been reached ( resistance levels etc ) or certain % gains made, the algos trigger sell orders en masse. So the spike is over, and the price levels fall back quite sharply with so much sudden supply flooding the market.
The same kind of thing happens with UK shares. If you take last Friday, when the news hit, half hour volume went up from about 0.2 m soon after the market opened, to 4.85m when the RNS was released, and the algos had therefore just kicked in. By 3pm on Friday the volume had fallen back to around 0.2m. Total volume on Friday was 18.5m and yesterday it was 3.7m. Today so far it's about 0.5m.
Trying to understand short term price action without paying any attention to volume is a bit like trying to fly a plane without instruments. Of course yesterday and today you will hear people saying ' oh, the market isn't convinced, as there are still hitches with the Special Purpose Certification etc.' The reality though is that the sharp spikes followed by sharp pullbacks are caused by algo driven short term trading/scalping which kick in typically when there is some kind of news, so that a particular share registers on that day as a high % gainer on abnormally high volume.
