Welltower's better-than-expected Q1 2024 FFO and sales figures, along with a notable year-over-year sales growth, are likely to positively influence investor sentiment and potentially lead to a short-term uptick in WELL's stock price. The earnings beat by 6.32% and the sales beat by 2.93%, coupled with a 19.09% increase in sales from the previous year, underscore the company's strong performance and operational efficiency, which are key drivers of stock price movements.
