Coppo: Stocks that jump on results keep trending for months

Reviewing the data for the last six reporting Seasons, I consider here how stocks that were either up or down on the day of reporting subsequently traded over the following four months. The results are very clear. 


Looking at stocks I covered in last 6 Reporting seasons:

  • Feb 2016 235 stocks
  • Aug 2016 312 stocks
  • Feb 2017 327 stocks
  • Aug 2017 310 stocks
  • Feb 2018 304 stocks
  • Aug 2018 304 stocks

Looking at stocks that were up & down on the day they reported, I have noticed over the years (and now have the hard evidence from the last 6 reporting seasons) that how the majority of stocks move on Day 1 generally determines where it will be 4 mths later..

So in the last 6 reporting seasons Day 1 Moves were

This shows how much stocks that were

  • Up on Day 1 went (first group on the left)
  • Were Down on Day 1  (3rd group in middle – all down)
  • Quite interestingly – you can actually see that most moves (be up or down) were very similar in each of the last 6 Reporting Seasons


In the last August 2018 RS the stocks that were up on Day1 had the biggest Day 1 reaction vs the previous 5 RS

  • You can see they rallied +6.2%, so when the market likes a result, more will try to get set on Day 1 as these stocks tend to stay up & in most cases keep going up in the 4 mths following

Now stocks that were Up day 1 when they reported

  • How they went…..

Source Coppo Report

  • In all 6 they closed up on average of +4.9% - almost all exactly the same
  • Then in 3 of the 5 RS or 60% of the time – the rise was double digit over the next 4 mths
  • Overall though the rise +4.9% Day 1 extended to be up +8.6% 4 mths later.
  • BUT Aug 2018 RS saw the Stocks up day 1 do something we haven't seen before - they were sold off (thks to big mkt selldown)  4mths later to be down -3.4% 
  • So in 5 out of the last 6 RS, being long these stocks up on Day 1 tends to be a good strategy, if you own before hold - but if not then you buy on the day they report.
  • So if you can’t decide to buy & you wait a few days or weeks – you may be paying more later on.

Down Day 1: Stocks that were down on the day they reported

Stocks that were down on the day they reported

  • Ok they were down on average -5.5% in the last 6 RS
  • In 5 of the 6, these stocks were still down, but had improved a little bit from where they were on the day they reported..
  • So many get smacked day 1 & then continue lower, but over time some bargain buyers come in & lift them. So the move 4 mths later is a lot better than where they were in the weeks & month after they reported.
  • But in most cases the bottom line is -  they have not rallied too much from where they were on Day 1…
  • On average these stocks that were down -5.5% on Day 1 were still down  -5.3%  4 mths later.
  • So in some ways its tells us there are "bargain buyers" who will go after some of these & buy on the weakness.
  • But in Aug 2018 they were smacked another -11.6%...
