Macy's Inc (M  ) shares are up over 15% in today's trading session already. Here are the factors that may be boosting the stock.

1. The $5.8 Billion Buyout Offer

An investor consortium, including Arkhouse Management and Brigade Capital Management, has proposed a $5.8 billion bid to acquire Macy's, amid increasing competition from digital retailers. The proposal at $21 per share is expected to help the company's market value.

Macy's has been facing intense competition from e-commerce platforms. It's possible the buyout bid is being understood by investors as the much-needed rescue plan for the retailer.

2. A Technical Signal

Macy's stock chart indicates a very interesting turn of events.

The 50-day SMA is on its way to cross over the 100-day SMA - indicating a Golden Cross - a bullish signal for traders in the market. Macy's stock has got a big bump from the buyout news, and investors could take the recent rally as market sentiment-driven. The fundamental story on Macy's remains muted.

The stock may be seen as moving up over the recent past but is down about 25% over the past year.
