Hi All, Iâve come across a rule of thumb statistic that 85% of the time, stocks tend to role sideways. This would mean 15% of the time, stocks tend to trend either upwards or downwards. My question is, would this imply stocks trend upwards 7.5% of the time and likewise downwards 7.5% of the time, or does this split work out differently in practice? If anyone has ideas on how this 15% should be split between upwards and downwards, I am all ears. Thanks in Advance for all responses. (Iâm aware itâs a general rule of thumb with no right or wrong answer that shouldnât be taken as gospel).
