AltaGas (TSX:ALA) Valuation in Focus Following Entry Into FTSE All-World Index

AltaGas (TSX:ALA) just made a new mark by being added to the FTSE All-World Index, a move that tends to catch the attention of both institutional investors and retail shareholders. This kind of index inclusion is not just a line in a press release; it can influence how investors perceive AltaGas, with funds that track the index potentially buying shares to match its composition. For anyone watching for shifts in ownership or liquidity, this event is worth noting as it can impact how the stock trades in coming months.

The backdrop to this inclusion is a year where AltaGas has already been building momentum. Shares have climbed 27% so far this year and are up 31% over the past twelve months, suggesting more investors are pricing in steady growth and perhaps a shift in risk perception. That said, recent months have shown only a modest uptick in price, which may reflect markets catching their breath after a strong run. The long-term trend remains firmly positive.

After climbing the ranks this year and landing a spot in a global benchmark, does AltaGas offer investors attractive value at today’s prices, or has the market already factored in its future growth?
