Morgan Stanley downgrades BP, cuts target for Shell

Elsewhere in the sector on the other hand, Total and Statoil had rocked the proverbial boat with their recently announced dividend hikes.

Indeed, it was chiefly due to the above that the broker downgraded BP, as it was limited to two 'overweights' in the sector.

Thus, while the broker's recommendation on Royal Dutch Shell stayed at 'overweight', that on Total was increased from 'equalweight' to 'overweight'.

The decisions from Total and Statoil marked an 'inflection point' for the sector, Morgan Stanley said, adding that it was "reflective of the improvement that insiders were seeing".

Yet while Total's dividend cover-by-free cash flow was seen reaching a "particularly strong" 155% by 2019, in BP's case that ratio was only expected to improve to around 95% in 2018 and then 110% in 2019.

Combined with a less robust balance sheet, that would see management prioritise debt reduction, Morgan Stanley said.

Even so, as confidence grew in its payout, Morgan Stanley expected the shares' dividend yield to fall.

Worth noting, the broker also revised its target prices for all three stocks lower, with BP's falling from 645p to 550p, Total's from €56.0 to €55.6 and Shell's from 3,040p to 2,830p.

The target price cut on Shell was despite the broker's forecasts calling for it to be the next to raise its dividend, with its free cash flow reaching $21bn in 2018 on an oil price of $64 a barrel, rising to $24bn in 2020 at $60 oil, resulting in FCF dividend covers of about 135% and 155% in each of those years.

"If history is any guide, BP's financial outlook is strong enough so that investors do not demand a yield much bigger than ~5.2% [from 6.2% at present], which is our target yield by end-2018. This still suggests a return prospect of ~23% – healthy but less strong that its two direct peers (Total and Shell)."
