Telstra Group Ltd (ASX: TLS) shares pushed to fresh highs, finishing Tuesday's session at $5.25 — a new 52-week high.
That caps off a strong run. The ASX telecom giant is now up around 28% over the past 12 months. By comparison, the S&P/ASX 200 Index (ASX: XJO) gained 9.7% over the same period.
So, what's driving the rally? In part, it looks like investors are leaning into defensive names. In volatile markets, companies with stable earnings and reliable dividends often come back into favour. And Telstra shares fit that bill.
But after such a strong run, what comes next?

Australian dominance
Telstra's biggest advantage is its dominant position in Australia's telecommunications market. It has a vast mobile and broadband network, along with millions of customers, giving it scale that competitors struggle to match.
Earnings are also relatively resilient. Telecom services are essential, which means demand tends to hold up even during economic slowdowns.
The company is also benefiting from its ongoing strategy focused on improving margins and monetising its infrastructure. Investments in 5G and network quality are helping support pricing power and customer growth.
Importantly, Telstra generates strong and consistent cash flow — a key factor behind its appeal to investors.
Pressure pricing, large investments
Despite its strengths, Telstra is not without risks.
Competition remains intense, particularly in mobile and broadband. Rivals like Optus and TPG Telecom Ltd (ASX: TPG) can still pressure pricing, especially in value segments of the market.
The business also requires ongoing capital investment to maintain and upgrade its network. These costs can weigh on free cash flow at times.
Another risk is valuation of Telstra shares. After a strong rally, the share price may already reflect much of the good news. That could limit upside in the near term if earnings growth doesn't keep pace.
Dividend appeal
One of the biggest drawcards of Telstra shares is its dividend.
The company is known for paying fully franked dividends, making it popular with income-focused investors. Its stable cash flow supports consistent payouts, and recent results have shown growth in dividends.
Last month, Telstra lifted its FY2026 interim dividend by 10.5% to 10.5 cents per share. If that momentum continues, it could deliver a fourth straight year of dividend growth.
That means that Telstra offers a solid dividend yield of around 4% at current price level.
What next for Telstra shares?
Broker views on Telstra are currently mixed.
The average 12-month price target sits around $5.20, which is slightly below the current share price. That suggests analysts see limited upside from here in the short term.
The most bullish broker has a price target of $5.60, implying about 7% upside. On the other hand, the most pessimistic view sits at $4.50, which would represent a potential 14% downside over 12 months.
In other words, while Telstra shares have delivered strong recent gains, analysts are divided on where it goes next.
