Picture supply: Rolls-Royce plc
It has been a exceptional few years for shareholders in Rolls-Royce (LSE: RR). In the course of the depths of the pandemic, the aeronautical engineer was on its knees. Rolls-Royce shares bought for pennies apiece as not too long ago as 2022.
Now although, the Rolls-Royce share value is over £7. It’s up 585% over the previous 5 years. With that form of momentum, may the shares probably go any larger – and ought I to purchase some for my portfolio?
Some potential boosters for enterprise progress
I do see some floor for optimism in terms of the potential ongoing progress of Rolls-Royce’s enterprise, each on the top line (revenue) and bottom line (profits).
Demand for plane engine gross sales and servicing stays excessive. The identical is true for energy programs and the defence enterprise. Final 12 months noticed underlying income progress in these areas of 24%, 11% and 13% respectively.
Whereas the civil aviation quantity stands out – particularly as it’s the largest enterprise – all of these progress figures are sturdy. With ongoing excessive demand, I reckon revenues may develop this 12 months too.
In the meantime, the corporate’s internet earnings grew final 12 months, however not by as dramatic an quantity as some buyers could have hoped.

Which will counsel that a few of the straightforward wins for the corporate have already been achieved in terms of reducing prices. Nonetheless, this 12 months the corporate has upgraded its medium-term targets, which have been already bold by the corporate’s latest historic commonplace. It’s now aiming for £3.6bn–£3.9bn of underlying working revenue by 2028 and an underlying working margin of 15-17%.
I’m nervous concerning the share value
However that’s removed from assured. Present commerce disputes threaten demand for brand spanking new engine gross sales. Sharp swings in some key currencies may additionally have an effect (adverse or constructive) when they’re reported again into Rolls’ reporting forex of sterling.
On prime of that there are ongoing dangers that concern me concerning the aviation trade as they are often signficiant however fall largely outdoors the management both of airways or engine makers. One other pandemic, giant terrorist occasion or warfare may abruptly ship passenger demand right into a headspin. That may possible be dangerous for revenues and earnings
With the proper margin of security within the share value, that will not hassle me. All shares carry dangers, in spite of everything: the sensible investor merely goals to cost them correctly.
However a rising share value has been pushing Rolls-Royce’s price-to-earnings ratio upwards. It now stands at 24.

That’s too excessive for my consolation in terms of having a margin of security.
Each investor is totally different, after all. I can nicely think about that if investor enthusiasm stays excessive or the corporate broadcasts additional excellent news, the share value could transfer up from right here.
From a long-term investing perspective although, the present share value will not be engaging to me and I can’t be investing.
