After looking at Toyotas stocks, I couldn't help but wonder why there was a sudden 800% increase on Google Finances graph in May 2020 and on the Yahoo Finance graph in April 2017. But the google one doesn't display the spike Yahoo does and visa versa. I can't see any news as to why these spikes must have happened and they're also not displayed on any other data I can see online. Can anyone offer any insight? p.s. this is for Toyota motor Corp listed on the LSE at roughly 2,000 yen a share not the one on the Nasdaq at roughly 187 USD as of 07/12/21
