A number of factors are thought to have contributed to the AAPL stock’s recent weakness, including a general lack of enthusiasm for technology and growth stocks.
Russia’s invasion of Ukraine also had a negative impact, along with ongoing concerns about supply-chain issues over the coming months.
For example, the stock was affected by China’s citywide lockdown of Shenzhen in early March due to a spike in Covid-19 cases, It has resulted in Apple’s supplier, Foxconn, halting operations in the region in response to the government-imposed closures.
For me, the main rationale behind shorting APPLE from the top is the fact that this giant company valuation is equal to the size of Japan's entire economy. If you can't see this being a bubble you shall stop investing or margin calls will come after you soon.
Not financial advice, only my personal views.
